Answer:

y = -3

Step-by-step explanation:

Step 1 - Subtract 5y from both sides of the equation:

5y - 4 - 5y = 9y + 8 - 5y

-4 = 4y + 8

Step 2 - Subtract 8 from both sides of the equation:

-4 - 8 = 4y + 8 - 8

-12 = 4y

Step 3 - swap the equation:

4y = -12

Step 4 - divide both sides of the equation by 4:

[tex]\frac{4y}{4} = \frac{-12}{4}[/tex]

y = -3

Hope this helps!
